Mangena is describing "best and most probable explanations" that Reeva was standing upright behind the bathroom door and then after the first shot she slumped down and sustained two further gun shot wounds.

The shooter - Pistorius - was "most likely" not wearing his false legs and was shooting at the bathroom door from a distance further than 60cm.

Col Ian van der Nest, blood spatter expert, is on the stand. He has 20 years experience with police forensic lab.

The prosecution wants Nest to confirm its sequence of gunshots.

He was asked to check for any evidence of blunt force trauma - ie the cricket bat vs gun shot wounds. He was also asked to check for bloodspots around the house - probably to rule in or out any evidence of a fight between Reeva and Pistorius.

Nest's evidence will be crucial to the prosecution's case - which is trying to establish premeditated murder.

He is talking about blood stains on the bannister, but suggests they were from Reeva's body being carried downstairs, rather than anything more sinister.
